Description

External chest compression device

Technical Field

The utility model relates to the technical field of medical machinery, in particular to an external chest compression device.

Background

Cardiac resuscitation usually requires the operator to be accurate, skilled, and in-place. And pay attention to the accuracy of the manipulation and pressing the correct part. The frequency and the subsidence depth of patients of different ages during pressing have different requirements, and the patients are stable, uniform and regular during pressing. The pressing position should not be too low to damage the liver and stomach. The pressure is proper, and the pressure is too light to push the blood circulation; the overweight can cause the sternum to fracture, resulting in pneumothorax, and particularly for children, the overweight or the underweight can easily occur, and the rescue is affected. Most of the existing heart pressing devices do not have a pressing depth limiting device, do not have corresponding adjusting functions to adjust the limit pressing depth, and inevitably cause sternum fracture of rescuees sometimes according to the experience of medical staff.

Some existing pressing equipment is complex in mechanism, a multi-purpose motor or an air cylinder and a sensor are used for pressing, but due to the fact that the equipment is complex, the pressing equipment is inconvenient to carry and inconvenient to use on an emergency site.

SUMMERY OF THE UTILITY MODEL

To the above situation, for overcoming the defects of the prior art, the utility model provides an external chest compression device, which effectively solves the problem that the patient keeps the posture and consumes too much physical power during the operation, thereby affecting the operation effect.

The technical scheme of its solution is, including the flat board of level form, there is vertical bracing piece dull and stereotyped both ends downside, has the vertical drum that runs through the flat board on the flat board, has vertical screw rod in the drum, through threaded connection between screw rod and the drum, there is annular arch drum upper end, and the screw rod lower extreme stretches out the drum and arranges the drum below in, and the screw rod lower extreme is fixed with the briquetting of level form.

The utility model discloses the structure is ingenious, can adjust according to the patient of difference and press the sunken degree of depth, is fine and serves the requirement of different age bracket patients, can press for a long time, reduces human error, guarantees to press the intensity, reduces the chest and presses down the emergence of complication, improves the recovery effect and the success rate of heart, simple and practical easily realizes, and adaptability is wide.

Detailed Description

The following detailed description of embodiments of the present invention is made with reference to the accompanying drawings.

By figure 1 to 3, the utility model discloses a flat board 1 of level form, there is vertical bracing piece 2 dull and stereotyped 1 both ends downside, has the vertical drum 3 that runs through flat board 1 on the flat board 1, has vertical screw rod 4 in the drum 3, through threaded connection between screw rod 4 and the drum 3, there is annular arch 5 drum 3 upper end, and 4 lower extremes of screw rod stretch out drum 3 and arrange drum 3 below in, and 4 lower extremes of screw rod are fixed with the briquetting 6 of level form.

For pressing convenience, the upper end of the screw rod 4 extends out of the cylinder 3 and is arranged above the cylinder 3, and the upper end of the screw rod 4 is provided with a horizontal pressing plate 7.

In order to avoid pressure sores or pressure injuries, the periphery of the lower end of the pressing block 6 is in arc transition.

The cylinder 3 is not separated from the flat plate 1.

The cylinder 3 is provided with scales for marking distance.

And a pressure spring is connected between the pressing block 6 and the flat plate 1.

When the breastbone pressing device is used, a patient lies flat, the flat plate 1 is placed above the patient, the supporting rods 2 on the periphery of the flat plate 1 are stably supported, the pressing block 6 is placed at a proper position in front of the chest of the patient, the pressing block 6 is enabled to prop against the patient, the pressing plate 7 is held by one hand, the cylinder 3 is screwed by the other hand, the distance between the upper end of the cylinder 3 and the flat plate 1 is adjusted, the distance between the cylinder 3 and the flat plate 1 is the maximum limit of depressed breastbones, the two hands are released and are overlapped on the pressing plate 7 and pressed downwards, when the annular bulge 5 at the upper end of the cylinder 3 is in contact with the flat plate 1, the pressing frequency.

The utility model discloses during the use, can adjust the range of pressing down through the distance between 3 upper ends annular bulges 5 of adjustment drum apart from flat board 1, especially to infant and children, the effectual degree of depth of pressing of having avoided is too big, also can make medical personnel relieved pressing down of courage, avoids the power to say too lightly and misses rescue time.

The utility model discloses the structure is ingenious, can adjust according to the patient of difference and press the sunken degree of depth, is fine and serves the requirement of different age bracket patients, can press for a long time, reduces human error, guarantees to press the intensity of pressure, reduces the chest and presses down the emergence of complication, conveniently carries, can improve cardiac resuscitation effect and success rate at the scene of suing and labouring direct use, simple and practical easily realizes, and adaptability is wide.
